In The Local Cell And In The Adjacent Cells. However, Cells Further Away Can Re-use That Channel Without Interference As The Subscriber's Handset Is Too Far Away To Be Detected.
The Automation Systems Can Control The "Hand Off" Of A Customer Handset Moving Between One Cell And Another So That A Call In Progress Continues Without Interruption, Changing Channels If Required.
In The Earliest Mobile Phone Systems By Contrast, All Control Was Done Manually; The Customer Would Search For An Unoccupied Channel And Speak To A Mobile Operator To Request Connection.
These Systems Have Dozens Or Hundreds Of Possible Channels Allocated To Them. When A Subscriber Is Using A Given Channel For A Telephone Connection, That Frequency Is Unavailable For Other Customers.
